SN74LVC157ANSRE4

Overview

The SN74LVC157ANSRE4 is a quad 2-input data selector/multiplexer from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and features a propagation delay of 7 ns. The device is housed in a 16-pin SOIC package and supports surface-mount installation. It functions across an extended temperature range from -40°C to +125°C, providing four independent circuits for signal routing.

Feature Summary

• Provides four independent 2-to-1 multiplexing channels for parallel data selection
• Compatible with mixed 3.3 V and 5 V systems due to input tolerance characteristics
• Operates reliably across industrial temperature ranges with low power consumption

Applications

• Data routing in mixed-voltage digital systems
• Signal selection in embedded control interfaces
• Function generation using data select inputs

Procurement Notes

Verify the E4 suffix indicates lead-free construction compliant with RoHS standards. Confirm the SOIC-16 package dimensions match PCB footprint requirements. Ensure operating conditions remain within the specified 1.65 V to 3.6 V supply limits. Validate thermal performance against the -40°C to +125°C rating during system integration.

Selection Notes

Select this component when low voltage operation between 1.65 V and 3.6 V is required. Choose the LVC series for faster switching speeds compared to standard LS logic. Opt for the SOIC-16 package if surface-mount assembly is preferred. Consider the extended temperature range for harsh environment applications.

Part Context

This part belongs to the SN74LVC157A series of multiplexers. The E4 suffix typically denotes environmental compliance, specifically lead-free manufacturing. It is part of the broader 74LVC logic family designed for low-voltage CMOS applications requiring high speed and low power dissipation.

Replacement Considerations

SN74LVC157ANSR is a compatible alternative within the same series. Verify pinout compatibility before substitution. Ensure voltage and temperature specifications align with current design constraints.
